Chrysanthemum plant

ABSTRACT

1. A new and distinct cultivar of chrysanthemum known by the cultivar name Revere and characterized particularly as to uniqueness by the combined characteristics of flat inflorescence form, reflexing slightly at maturity; pompon inflorescence type; two-toned red bronze and yellow bronze inflorescence color; diameter across face of inflorescence up to 2.75 inches; permanence of inflorescence ranging from 14 to 21 days; medium plant height; semi-upright branching pattern; average natural season flowering date of September 30 and average flowering response period of 7 weeks in photoperiodic controlled flowering programs.

The present invention comprises a new and distinct cultivar ofChrysanthemum morifolium, Ramat., hereinafter referred by the cultivarname Revere (No. 74045001).

Revere is a product of a planned breeding program which had theobjective of creating cultivars with small pompon inflorescence type,short height, spreading branching pattern, durable inflorescence, short(6 to 7 week) flowering response period, and adaptability of bothnatural season outdoor flowering and controlled greenhouse floweringprograms.

Revere was originated from a cross made in a controlled breeding programin Barberton, Ohio in the year 1973. The male, or pollen parent, was No.73337003 (unnamed seedling), a red bronze pompon originated by thepresent inventors from a cross between No. 72074M01 (unnamed seedling)and No. 72018003 (unnamed seedling). The female, or seed parent ofRevere, was No. 73247002 (unnamed seedling), an orange bronze pomponoriginated by the present inventors from a cross between No. 72037009(unnamed seedling) and No. 72018003 (unnamed seedling).

Revere was discovered and selected as a flowering plant within theprogeny of the stated cross by Walter H. Jessel, Jr. on May 4, 1974 inan outdoor field in Ft. Myers, Florida.

The first act of asexual reproduction of Revere was accomplished whenvegetative cuttings were taken from the initial selection in July, 1974in a controlled environment in Barberton, Ohio by a technician workingunder formulations established and supervised by William E. Duffett andWalter H. Jessel, Jr. Horticultural examination of selected unitsinitiated Oct. 10, 1974 has demonstrated that the combination ofcharacteristics as herein disclosed for Revere are firmly fixed and areretained through successive generations of asexual reproduction.

Revere has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity, and daylength. Thefollowing observations, measurements, and comparisons describe plantsgrown in a field in Barberton, Ohio under conditions which are generallydescribed in Local Climatalogical Data, Annual Summary with ComparativeData, Akron, Ohio. U.S. Department of Commerce, National Oceanic andAtmospheric Administration, Environmental Data Service, Washington, D.C.1974, 1975 and Tables of Sunrise, Sunset, and Twilight. Supplement tothe American Emphemeris, 1946, U.S. Naval Observatory, Washington, D.C.,pg. 103.

The following traits have been repeatedly observed and are determined tobe basic characteristics of Revere which in combination distinguish thischrysanthemum as a new and distinct cultivar:

1. Flat inflorescence form, reflexing slightly at maturity.

2. Pompon inflorescence type.

3. Two-toned red-bronze to yellow-bronze inflorescence color.

4. Diameter across face of inflorescence up to 2.75 inches.

5. . Permanence of inflorescence ranging from 14 to 21 days.

6. Medium plant height.

7. Semi-upright branching pattern.

8. Average natural season flowering date of September 30.

9. Average flowering response period of 7 weeks in photoperiodiccontrolled flowering programs.

The accompanying photographic drawings show typical inflorescence andfoliage characteristics of Revere with colors being as nearly true aspossible with illustration of this type. Sheet 1 is a color photographof Revere. Sheet 2 is a black and white photograph showing three viewsof the inflorescence of Revere. Sheet 3 is a black and white photographshowing the foliage of Revere at three stages of growth.

Of the many commercially available cultivars known to the presentinventors, the most similar existing cultivars in comparison to Revereare Brown Eyes (No. 21660E12; unpatented) and Pancho (No. 21610E04;unpatented). Reference is made to attached Chart A which comparescertain characteristics of Revere with the same characteristics of BrownEyes and Pancho. General comparisons are as follows:

1. In comparison to Brown Eyes, Revere has different inflorescencecolor, earlier natural season flower date, more upright branchingpattern, taller plant height, and larger diameter across face ofinflorescence. The inflorescence type, inflorescence form, andcontrolled flowering response of Revere are similar to those of BrownEyes.

2. In comparison to Pancho, Revere has different inflorescence color,different inflorescence type, earlier natural season flower date, tallerplant height, and larger diameter across face of inflorescence. Theinflorescence form, branching pattern, and controlled flowering responseof Revere are similar to those of Pancho.

In the following description, color references are made to The MunsellLimit Color Cascade, 1972 edition. The color values were determinedbetween 10:30 and 11:00 A.M. on Oct. 14, 1975 under 120 foot-candlelight intensity at Barberton, Ohio.
